The child was hit while walking across Pleasant Street with his mother, Worcester police said in a statement.

Police said the boy, whose name was not released, and his mother were crossing inside a marked crosswalk around 8:15 a.m., after being signaled by a crossing guard, police said. They were in the middle of the road when the boy was hit by a Ford Explorer and flung five feet.

He was taken to a local hospital and treated for his injuries, police said.

The driver of the Explorer fled the scene of the crash, police said.

Under four hours later, the vehicle was spotted by an officer at the corner of May and Pleasant streets. Police said the vehicle had front-end damage.

An Uxbridge woman, 27-year-old Gina Amore, was charged with failure to yield to a pedestrian in a crosswalk and leaving the scene of a personal injury, police said. She will be arraigned in Worcester County Court on Wednesday.
